A Taxonomic Study Of The Catostomidae Of Utah Lake With Notes On The Fish Population, Lyle Junior Lowder
A Taxonomic Study Of The Catostomidae Of Utah Lake With Notes On The Fish Population, Lyle Junior Lowder
Theses and Dissertations
During the period from October 1950 to March 1951 a study of the taxonomy of the Catostomidae of Utah Lake was undertaken. Throughout this study information was collected on the numbers of suckers taken by some of the fisherman. From the data gathered it appears that the three species of Catostomidae cringinally named from Utah Lake are still there. The external morphological features of these fish are not recognizable unless they are observed very carefully. The most outstanding external characteristics used to differentiate the species are the mouth, lips, papillae on the lips and the general shape of the head. …

A Preliminary Study Of The Distribution Of Fleas In Utah Known To Be Capable And Potential Vectors Of Plague, Dorald M. Allred
Theses and Dissertations
Plague outbreaks in the past have been disastrous where domestic rats and their fleas of certain species were common. Plague has been known to occur in most parts of the world (Robertson 1923), and has occurred as human epidemics for many centuries (Dubos 1948).
Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Theses and Dissertations
During the period of October to April of the winter of 1950-51, an ecological study was undertaken of a population or passerine birds wintering in a segment of the Utah Lake Shore. Available winter weather data indicated that although such factors as precipitation, temperature, and wind may often be severe, they are not critical enough to prevent a fairly large population of passerine birds from spending the winter months in the study locale. Five fairly distinct plant communities can be recognized in the area. There is evidence which indicates that certain passerine bird species are especially dependent on a particular …

An Ecological Study Of A Sphagnum Lake In The Subalpine Forest Of The Uinta Mountains Of Utah, Howard C. Stutz
Theses and Dissertations
A study was made of the ecology and floristics of a small bog lake referred to as Moss Lake, in the Grandaddy lakes region of the Uinta Mountains , Utah . Three consecutive summers, 1948, 1949, and 1950, were spent in collecting the data presented in this study. Throughout the study the following ecological measurements were made: 1. Water 2. Soil 3. Macroscopic vegetation 4. Plankton 5. Macroscopic animal forms.
